In section 2.6 it reads, "The id attribute assigns a name to an
element." I find this assertion inaccurately as names usually things
given to things liberally without regard for uniqueness.
Given that "id" is short of identifier anyway, I personally think that
statement should read:
"The id attribute assigns an identifier to an element."
If the change is accepted, then the proceeding sentence would also need
to change from:
"The given name must be unique in the binding document."
To:
"The given identifier must be unique in the binding document."
